Leaves drooping

Honestly to me they look great. They are bushy, green, and solid in stature. It looks to me like you have some healthy seedlings. All my grows are all around the same humidity as yours with no ill effects. I personally think your leaf droop is good, it looks like the leaves are growing a bit faster than the leaf petioles are able to support. Your ladies have plenty of light, as soon as they develop a bit more root structure that should disappear. As the previous answer said, after a good water pick up the pot and remember how heavy it is, and do not water until it feels very light, or has a slight weight to it. Happy growing and good luck! Cheers.
